PAPER-BOX MACHINE.

SPECIFICATION forming part of Letters Patent No. 503,907, dated August 22, 1893.

Application filed January 31, 1893- Serial No. 460,370. [No model.)

To all whom it may concern.-

Be it known that I, LEWIS F. FALES, a citizen of the United States, residing at Walpole, in the county of Norfolk and State of Massachusetts, have invented new and useful Improvements in Paper-Box Machines, of which the following is a specification.

This invention, for improvements in maohines for making paper boxes, more particularly relates to devices for closing and gluing or cementing the flaps which constitute the bottom, or one end wall of the box, the other end thereof, as understood, being left open, as common in a well known form of telescoping box or case.

The purpose of this invention is to devise a machine which will perform the indicated work efficiently and with a satisfactory degree of speed,-and which machine will, furthermore, be readily adjustable and adaptable to the reception of interchangeable parts for operation upon various sizes of boxes.

The invention consists in certain several and various combinations and arrangements of parts, and the constructions of certain of the parts, substantially as will hereinafter-appear and be covered in and by the claims.

An embodiment of the invention as at present carried out and practiced is illustrated in the accompanying drawings in which- Figure l is a plan view of the machine. Fig. 2 is a perspective view of the adjustable supports for the glue rollers. Fig. 3 is a sectional elevation of the machine taken on the line 33, Fig. 1. Figs. 4 and 5 are side views of cams employed in the machine to which reference will be hereinafter made. Fig. 6 is a sectional view in detail on the line 6-6 of Fig.3. Fig. 7 is a view substantially in elevation showing an adjustable support for the glue or cement receptacle. Fig. 8 is a perspective view of one of the carriers or formers and the folding and gluing devices, on a larger scale. Fig. 9 is a longitudinal, vertical, sectional view of parts of the folding devices as taken on line 99, Fig. 8, said view also showing the position relative thereto of the flaps of the box-being folded thereby. Figs. 10, 11, and 12 are vertical sections taken across the folding devices on the lines 10-10, 1l-11, and 12-12, respectivelyof Fig. 8, illustrating the different stages in the folding operation.

named devices, they, however, being understood as having come into different relative positions, as will be hereinafter explained. For olearness of illustration the front one of the pair of arms which carries the stripping, or box withdrawing device is understood as removed,the supporting stud for the stripper being shown as in vertical section taken just inside of the front carrying arm. Fig. 15 is a partial sectional view, as taken horizontally on the line 15-15, Fig. 14. Fig. 16 is a perspective view of one of the blanks or partially formed boxes,with the unfoldedand unsecured flaps.

Similar characters of reference indicate corresponding parts in all of the views.

The form of box-blanks such as is operated upon by this machine and as shown in said Fig. 16, has four flaps which, when folded and stuck, constitute the bottom of the box. The machine operates to fold the one side flap, 21, inwardly, then the'other,22, upon it, and then the other pair of flaps 23, 24, receive a layer of glue or cement and are folded inwardly, the

one toward the other, and both upon the firstpair of folded flaps. The folded and glued flaps are then acted upon for the purpose of squaring the box at the corners, and pressure is then applied to fix and retain the relations of the stuck flaps after which the box is automatically discharged from the machine.

I will now proceed to describe the machine in detail and, referring to the drawings A will be regarded as the mainshaft although B is the driving shaft, the latter reoeivii'ig its rotation through belt and pulley and has a pinion-gear, 25, thereon which meshes into the larger spur-gear 26, of the main shaft. The shaft, B, rotates several times to one rotation of shaft, A.

0 represents an internal gear which is mounted on suitable supports for rotation about a fixed axis this gear receiving its comparatively slow rotation by the mesh which the pinion-gear, 27, of the main shaft A, has therewith. It will be noticed that upon a shaft, D, a frame D is mounted for rotation which comprises several, here four, radial arms a in the form of a cross and the inter-- nal' gear 0, is clamped to this cross-shaped frame. This is a practical and preferred manner'of mountingthe internal gear for its rotational movement but limitation isnotto he; Each of the rathe carrier coincident with the folding lines 5 of the flaps.

It will be noticed that one or more ducts, '29, are for ed hrough the a i s, th y,

extending fromthe outer endlongitudinally and then transversely, terminating inwardly beyond the portion of the carrier which is inclOSfid by the paper blank. These are to prevent the establishment of a vacuum within the box after its bottom has been closed upon thoar ier and fo me hi h m gh inter e with the easy discharge of the box, J

Now it is un erstood tha t a t n a standing, as the machine is here represented f at the rightthereof, places the blank upon the adjacent carrier, 12, with the flaps in their naturallongitudinal, or radial extension;-

and th b ank i a e rough a po t of a revolution to the folding devices at the left which wil he now describe- .1 r fe e e e ng directed to Figs. 1, 3, 8 and 9 to 12,

d epresents a p at hich s a anged ad jacent" the pat of the ou e end of ach 0 1' theoar ie s, b, n t s plate ex e ds abou parallel and i Proximi y to sai p o wardly and to the right as more clearly indicatedin Fig. 3. Now the'forward flap, 21, in being brought against the upper edge of the folding plate, (1, is turned thereby toward the nd f the carrier, s pla n y ndicated in, g. i

9, About concurrent with this action the folding blade, f, has a quick downward and forwardimovement to overtake the retreating carrier, and striking against the flap, 22, also folds it inwardly. This folder, f, is mounted upon an arm, 30, which has a rocking movement upon the shaft, 32. This rock-shaft, 32, has a crank-arm, 33, to which is connected one end of a thrnst-rod, 34. This thrust-rod has its'other end, which is provided with the stud and roller, as seen at 35 maintained by the spring, 36, against the cam, 37, which is on' the main shaft,-A. The blade,f, will be reciprocated in proper time each time thata carrier with a plank thereon is brought to the o n Plate, h ma haf nd a 1'0- 1 tating fohr times to one of the internal gear.

The next operation of the machine is to turn a the other pair of flaps, 23 and 24, outwardly,

as-seen in Fig.8. It will be perceived that the upper extremity of the folding plate, d

is approximately the width of, but no wider than,-the width'of the box between flaps 23 and 24, and this upper portion has the downwardly and forwardly divergent parts 39', 39,

formed thereon or attached thereto. In this illustration, Fig. 8, they are shown as in the form of bowed wires but this is only an immaterial structural detail. It will be apparout by reason of the form and position of these divergent parts, 39, 39, relative to the path of the flaps, 23 and 24, that the flaps will, soon I after having passed the upperend of the plate, .61, be laid outmoreior less nearly in outward right angular extension from the sides of the body of the blank and so-that they may next run upon the peripheries of the rollers, E E, which turn in the receptacle F, for thecement,

; gum, or other adhesive employed. The next operation of the machine is to turn the outwardly extended and now glue-covered side flaps inwardly tolie upon the already inturned flaps, 21 and 22 and this is accomplished by the carrying of the flaps under the strips at each side of the course of movement of the extremity of the carrier all so that the flaps are gradually drawn toward each other and finally come adjacent thefirst folded flaps in the manner indicated and as will be clearly understood without extended description on reference to Figs. 10, 11 and12., Each of these strips indicated at g, g, is of itself formed with or has a supplemental part as g which is inwardly deflected or inclined, the extremities of these parts, as seen'in Figs. 8 and 12, standing quite closely together and they are also brought into closer proximity to the path of the end of the carrier than are the more rearward portions of the said parts, g g. The downwardly and forwardly extended portion of the plate, (1, (regarding the right hand portion of the machine as the front) servesto hold the first folded flap from unduly springing outwardly away from the end of the carrier during the time the outturned flaps are being guinmed and then being in-turned. This plate has the narrowed forward extension, (1 so that the space bea tween this portion and the convergent members, g 9 may be ample to permit the inward turning of the flaps; and this narrowed extension terminates somewhat to the rear of the ends of the Parts gand 9 so as to constitute no impediment to the final closing together of all of the flaps as occurs by the sliding impingement which the said glued flaps have with the forward extremities of the convergent members, g 9 just previous to the passage of the carrier and box thereon to the pressure rolls which are-indicated in plurality at h. It will be furthermore perceived that the "strips or plates, g, g, have their forward ex- IIO the bottom corners of the box, serving as guides and as angular pressure fingers thereupon. 'The parts, d, g, 9 with the described supplemental or conjunctive devices all receive support from the horizontal transverse brace-rod, 42. By adjustment, transversely, of the strips, 9, g, and auxiliary members carried thereby, these devices may become adaptable to different sized boxes. These parts may be adjustable by reason of the lugs, 43, which are formed on or secured to the strips, g, g, having sliding engagements with the aforesaid snpport-rod, 42, and the set screws, 44, for holding them in adjustment.

The series of pressure rolls, h, h, are arranged axially parallel in proximity the one to another and all to the circular path of the end of the carrier upon which is the folded end of the box. The first of these rollers, just as the carrier comes thereover, is given a slight upward impulse through the means to be now described.

The gudgeons h of the first roller, are constrained in suitable guides therefor at each end thereof, for the upward movement and to the gudgeons are engaged the upper portions of depending bars or links, h Connected to these bars, 72 is another link, h, its other end being connected pivotally with the transverse bar or shaft, M, which is supported between side members of the framing. It will be apparent that these parts, h, h amount substantially to a toggle and the actuating means therefor consist in a quite powerful and active spring, 45, applied so as to upwardly force the first roll, h, and the toggles with considerable power, and the cam-operated thrustrod, h, for maintaining a pressure-roll for the greater portion of the time in its lowered position. The said thrust-rod,h ,has its lower end pivoted to the link-member, 77. and carries at its upper end a friction roller against which the cam, 15, has its forcing bearing. This one here employed is a multiple cam, that is to say it has four cam surfaces corresponding to the four carriers embodied in the machine as here shown. Each cam is so timed that as the end of the carrier comes over the first roll edge the most prominent cam portion passes the friction roller of the first rod permitting the latter to rise under the reaction of the aforesaid spring to impart the hard and initial squeeze to the folded and gummed bottom flaps. The succeeding rollers of the series have less pressure their purpose being to merely exercise such contact upon the now stuck flaps as to prevent their opening up be fore the cement or gum has become sufficiently set. Each of the last four rollers in the series, here shown, has its gudgeons orjournals extended into the externally squared boxes, j, which are fitted for approximately vertical movements in the apertured support, it, therefor. This apertured support under the boxes has respectively therefor sockets, as seen at k within which are the springs, which are set for upward reaction against the boxes, j. The degree of compression of the spring may be varied by turning in or out the screws, 70 The extent of upward movement of the rolls may be regulated by the adjustable stop screws, Z, so that the normal position of the upper portions of the roller peripheries may be properly relative to the path of the ends of the carriers, 1), as most efficient for the performance of the work to be performed by the machine. The box is next withdrawn from its carrier block by means which will be now described, reference being had to Figs. 1, 3, 13, 14, and 15.

m represents a yoke or stirrup-formed part carried at the rearwardly and upwardly extended extremity of a lever, m which is mounted upon the rock-shaft,m The rocking motion is imparted to this shaft in one direction through the connection with the radial arm, m thereof, of the forward end of a thrust-rod, m the rear extremity of which has a roller engagement with the cam, 50, on the main shaft A and which cam is clearly shown in side view in Fig.4. The rocking movement is imparted in the other direction by the spring, we, applied for a rearward reaction relative to the rock-shaft arm, m, by having one end connected thereto and its other end connected to a fixture of the machine. The upwardly and rearwardly extended arms of this yoke, m, stand opposite each other at each side of the plane of travel of the carriers, 6, b, b, b and each has fixed to its extremity a transversely and inwardly extended stud or bar, at, withits inner end headed, as indicated, at M, in Fig. 15. Acylindrical part,n is fitted upon the extremity of the stud, n, the same being bored with axial openings of two diameters wherebya suitable chamber for the enlargement, n is provided and an aperture for the passage of the portion of the bar next thereto; the junction of the bores of different diameters also constitutes an internal seat or shoulder, a, for limiting, by its engagement with the stud enlargement, m the axial movement of the said part, 01 This part has, at its inner end, a lip, n which has a straight edge, as indicated in Figs. 13 and 14 and which is extended slightly beyond the end of the part, a and which also rearwardly is beveled, as seen at n. The parts, a which may, with propriety, be termed fingers are normally inwardly pressed by the spring, a, to the extent permitted by the enlargement or stop, W. as the carrier is moving forwardly and upwardly after the sticking and roll-pressing of the flaps of the box-blank, the yoke, m, is rearwardly and downwardly moved and in meeting the carriers the fingers, M, are, by reason of said bevel formation, 76, caused to so recede on their studs, 07., as to allow the contact lips, 07?, to come against the opposite faces of the carrier. Now, while the carrier continues its forward movement the fingers will have come to the position relative to the opposite sides of the carrier indicated in Fig.

compound of the revoluble movement of the l '14, and at or about this instant the cam, 50, causes such a forward movement of the yoke as to move the fingers exactly, or approxim'ately, in themedian longitudinal line of the There is to this end, of course, the

carrier and of the swinging movement of the yoke, but the elfect for the withdrawal of the tionary and the fingers moved in straight lines longitudinally against the opposite sides thereof.

The glue rollers,E,E,.are driven ,primarily, through means of the rotation of the shaft, G. As shown, each. roller is mounted on a shortcounter-shaft, H, which is geared to the shaft, G, and which counter-shafts have suitable bearing supports which are carried by the bracket arms, o',0, of separate boards-or bars, 0, 0, which have tongue-and-groove engagements witha fixed bar or part, p, of the frame. This fixed, supporting bar, p,-has the slots,'p p and the bar, 0, has the screwspi'ndle o rigidly secured thereto which passes through the slots, beyond the outer face of the slotted bar receiving the set nuts, 0 thereon. Each of the movable bars, 0, 0, has a Tlug, q,'and these lugs have screw-tapped aligned apertures in and through which engages the right and left screw-threaded rod, g with hand-wheel thereon for convenience of securing its rotation; By loosening. the nuts and turning the screw-rod, the rolls will be brought to the proper adjustable separation to conform to the work desired to be performed by the machine.

The receptacle, F, for containing the glue or cement is surrounded by a steam jacket with which are connected steam ingress and egress pipes. No novelty is, however, claimed to exist in this apparatus for maintaining the adhesive at the desired high temperature.

To adapt the machine for operation on tubular blanks for boxes of a given cross sectional size but of varying lengths, the set screws, 60,

for the slotted, adjustable gages, 28, are loosened and the gages moved endwise of the former and carrier, I). These gages, by being in the form of angle-lugs, each with its slot,

the olfset member, 62,may be readily slid along the corners of the rectangular carrier with the abutment faces, 63, of'the gages,

placed on the arms, a, of, the frame, D by carriers having greater or smaller cross sectional dimensions for. the purpose of rendering the machine adaptable for operation on screws, bfipass through these extended parts, a b and hold them so long as desired, as one. The ejector fingers, n n may be made to 61, arranged parallel with the inner face of' always parallelwith the end of the carrier.
